PATENT OF ICE;

,SILO.

To all whomiv may concern: Be it known that 1, CHARLES W. McCLURn,

a citizen of the U nited States, residing at Saginaw, in the'county of Saginawand State of.

'and readily assembledwithout the aid of skilled labor, that will serve asa gage or: guide for setting up the silo, and will form a secure support for the silo doors' and provide a support for the silo-hoops. Y

With these and certain other advanta es in view, which will appear. later in thespecification, my invention consists in the parts, their combinations, and the thereof herein set forth. I The device is illustrated in the accompany? ing drawings, in which Figure 1 is a front elevation ,of one of the door-sections, showing part of the silo-frame and a preferred method of fastening the door to the frame. Fig. 2 is a similar view showing the method-of snpportin the hoops of the silo where they cross the s o-opening and of holding the door-frame securely in place. Fig. 3 a'horizontal section of the silo door and frame broken away inv part. The door-frame consists in a air of verti: cal members A. A, each preferab y made of a single piece of angle iron or a metal bar of equivalent shape. It is preferably fastened, as shown in the drawings, to the edge of the stave'at the sideof the silo-opening. In the form illustrated in the drawings, where the side members are formed of angle-iron, the,

outer face of one leg of the an 1e rests against the edge of the stave C, an the other leg,' which is practically flush with the outer surface of the stave C, projects over the opening to form a guide along which the'door E may he slid vertically. Pressure against the door produced by expansion of the ensilag'e within presses the door out against the angle, and the greater the pressure from. within the tighter the opening is closed.

j The side bars A A are bound together at Specification of Letters Patent. 1 Application filed April 27, 1205. Serial'No. 257,645.

other suitable means. The bars B where they cross the opening of the silo are prefer:

'The hoop firmly holds the ends B of the bars Ba' ainst the stavesO," thus relievin the bolts of 7s stlrain d'ue li -expansion of't emateri'al in the s o. Thefcombination ofgthejtwo vertical side 'bars"A"A= and the cross' bars B B, which are 'rivetedgtoithem, forms -a rigidframe for the s1lo+opening.- These parts areusually shipped assembled, it being only necessary'when 'con- 'structing a silo to setup theifron frame for the opening, erect the 'staves',;-;Iand bind the silo in'the usual mannerb .the'hoops DD. A silo-frame made as ag fidescribed will ance between the side"barsii-A, A will not de p prevented from so doing bylthefcross bars Theensila e is reventedfromiiolming in contact wit the ars A A, bei;n'g-covered from within by the :doors E. The-frame ofthis construction is rigid and one side. of the frame cannot dropldown and throw the frame out of shape.

Eac of the side members A' has large bearing-surface against the edge of the stave C, and by reason of thisdarge bearing-surface the bolts B" are relieved of the transverse strain which would, if it were not for the large 9 5 bearing-surface, be brou ht upon them by reason of the crushing e ect of the 'staves when the become soaked with moisture.

What claim as my invention, and desire to secure by Letters Patent, is as follows:

1. A frame for silo-openings, comprising in combination a pair of upright bars of L-section, each bar being arranged with one of its members flush with'the face of the adjacent silo -staves; a plurality of transverse bars 2. The combination with the staves of a silo, of ametallic door-frame therefor relative to which frame the stave's are erected, said frame comprising a pair of continuous angleirons, one flan e of each of which abuts the end staves of t e silo, the remaining flange of which projects over the o ening in thesilo, to form seats or guides for t e doors, and braces extending between the angle-irons and superposed upon the outer faces thereof, the ends of the braces overlying the end staves of the silo and separate .means for. securing the braces to the outer faces of the angle-irons and to the end staves.

3. In a silo provided with a continuous opening, the combinati'onof a door-frame comprising a pair of vertical angle-irons line ing the walls of the opening from end to end, one flange of each of the angle-irons abutting the Wal and the remaining flange overlapping the opening to form seats for-the doors,

races connecting the angle-irons, the braces applied to the outer faces of the angle-irons and overlapping that portion of the S110 ad j acent the frame, and separate means for securing the braces to the angle-irons and to the silo respectively.

In testimony whereof Iaflix my signature in presence of two witnesses.
